History of Gradall Excavators
There’re some GRADALL Excavator Manuals PDF above the page.
The legendary Gradall excavator, the world’s first telescopic excavator, was created by brothers Ray and Koop Ferwerda in the early 1940s.
In 1944, the brothers received a patent for their development, after which they signed an agreement for the production of excavators with Warner & Swasey Co. from Cleveland, USA.
Over the years, other concerns have entered the Gradall Division: one for the production of tractors for cranes and dump trucks.
Another for the production of small backhoe loaders; the third is for the production of vehicles and hydraulic cranes.
Gradall later changed owners several times: Bendix Corp., GBKS, ICM Industries, Morgan investment group, Lewis, Githens and Ahn.
In 1999, Gradall acquired by JLG Industries.
Finally, in 2006, the company became part of the Alamo Group Inc.
